P2007 on Subaru by model: symptoms, diagnosis and fix
Turbo WRX intake manifolds carry tumble generator valves — butterfly plates in each runner driven by a small electric actuator with a position sensor. The original valve shaft material corrodes from EGR/condensation and binds, or the actuator motor/sensor fails, and the ECU logs TGV stuck-open/stuck-closed codes (P2004-P2007, sometimes P2016/P2017 position sensor codes). The car goes into a reduced-power mode. Subaru acknowledged the shaft corrosion in TSB 02-182-19 and revised the shaft material. It affects the FA20DIT WRX (2015-2019).
Common Symptoms
- Check engine light with P2004-P2007
- Significant loss of power / limp mode
- Rough idle
- Intermittent code that returns after clearing
How to Fix
Confirm by disconnecting the actuator and rotating the valve by hand — a gritty or stuck shaft means the TGV assembly is seized. Replace the affected TGV assembly with the revised-shaft part (Subaru does not sell the motor or sensor separately). Some owners delete TGVs with aftermarket housings, which requires a tune. Out of warranty there is no free remedy; the TSB is a diagnostic aid, not a campaign.

Frequently asked questions
What does P2007 mean on a Subaru?
P2007 stands for "Intake Manifold Runner Control Stuck Closed (Bank 2)." This generic powertrain code sets when the PCM detects that the intake manifold runner control (IMRC) for engine bank 2 is stuck in the closed position. The IMRC uses movable flaps/runners to vary intake air velocity for optimal performance and efficiency across the RPM range, so a stuck-closed runner means the system cannot open the flaps as commanded. Bank 2 is the cylinder bank that does not contain cylinder #1. On Subaru it is documented across 1 model: WRX.
What are the most common causes of P2007?
The most common causes of P2007 are: Failed or seized intake manifold runner control actuator/solenoid, Carbon buildup or sticking/binding intake runner flaps or linkage, Broken, disconnected, or stuck IMRC vacuum/mechanical linkage, Wiring or connector faults (open, short, corrosion) in the IMRC circuit, Faulty intake manifold runner position sensor, Defective intake manifold (warped/broken runners) or, rarely, a faulty PCM. The specific cause varies by vehicle.
How much does it cost to fix P2007 on a Subaru?
Published repair estimates on Subaru range from $350 to $1,200 depending on the model and root cause. If an issue mentions a recall or campaign, check your VIN with the manufacturer or NHTSA and confirm eligibility and coverage with a dealer.
